RECORDING WEIGH-BEAM FOR SCALES.

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed May 13, 1907. Serial No. 373.252.

T 0 all whom it may concern:

Be it known that I, WILLIAM N. GILBERT, a citizen of the United States,residing at Binghamton, county of Broome, and State of New York, haveinvented certain new and useful Improvements in Recording Vleigh- Beamsfor Scales, fully described and repre sented in the followingspecification and the accompanying drawings, forming a part of the same.I

This invention relates to recording weigh beams for scales, the objectof the invention being to provide a simple, compact and eificientconstruction of weigh beam and printing devices.

For a full understanding of the invention a detailed description of aweigh beam embodying the same in its preferred form will now be given inconnection with the accompanying drawings forming a part of thisspecification and the features forming the invention specificallypointed out in the claims.

In the drawings :F igure 1 is a front elevation of a portion of theweigh beam, with the main poise partly in section. Fig. 2 is ahorizontal section on the line 2 of Fig. 1. Fig. 3 is an end elevationwith the main beam in section. Fig. 4 is a cross section on line 4 ofFigs. 1 and 2 showing the parts in position at the end of the printingoperation.

Referring to the drawings, A is the main scale beam, B the main poisemounted there 011 by rollers 10 and locked in position thereon by aspring pressed stop pawl 12 engaging notches 13. The main beam A hasflange 14, on the upper surface of which is a type bar carrying the type1 for printing a part of the weight, the thousands in the scaleillustrated. The type 2 for printing the hundreds in the scaleillustrated are carried by printing wheel C, which is carried by pivotstud 15 mounted to rotate in the main poise A, and provided with a thumbpiece 3 for rotating it. The type wheel O carries a gear 16 which gearswith the lower side of the auxiliary poise a, so as to move the latteras the type wheel is rotated, the auxiliary poise carrying the pointer 4which moves over index plate 17 on the front of the main poise. Theauxiliary poise is yieldingly held in position by spring roller 5engaging teeth on the top of the auxiliary poise, and is held inposition and guided by bar 1) moving with it on the main poise.

Above the type 1, 2 is the impression roller 0 which is mounted in asliding carrier 18 spring pressed inward by spring 6 and provided with ahandle h for moving the roller for printing. The printing pressure on cis secured by the cam slots 7 in brackets 19 which raise and lower theroller 0 in slots in the carrier 18 in which the roller is mounted. Theticket x is introduced above the type and below the roller 0 throughticket slot 8 formed in a swinging carrier (Z, which is pivoted on thestud 15 so as to swing between the positions of printing tare and grossweight, being normally held in position for printing gross weight, asshown in the drawings, by spring 9. By moving the ticket carrier d tothe left from the position shown in Fig. 1, the ticket will be broughtinto position for printing tare weight. It will be seen that thismovement of the ticket carrier to the left in Fig. 1 for printing tareweight, forces the pawl 12 into the notches 18, so as to hold the poisemore strongly, instead of withdrawing the pawl with liability of movingthe poise, as would be the case if the ticket carrier moved to the rightfor tare weight. This is an important detail feature of the constructionshown. The ticket holder is stopped in proper position for printing thetwo weights by stop 9 in a slot in the holder.

The operation of the construction will be understood from the drawingswithout a detailed description, Figs. 1 to 3 showing the parts inposition with the printing roller 0 moved inward past the type 1, 2 byspring 6 and raised by the cam slots 7, while Fig. 1 shows the roller 0drawn out and after pressing the ticket w against the type for printing.The use of the main poise and auxiliary poise, and their relation to theprinting type, is the same as in previous weigh beams, the type for theauxiliary poise, however, being carried on the printing wheel instead ofon the auxiliary poise itself.

It will be understood that the invention is not to be limited to theexact form or arrangement of parts shown, but that modifications may bemade therein while retaining the invention as defined by the claims.

What I claim is 1. In a recording weigh beam, the combination with themain beam and type there- 011 and the main and auxiliary poises, of atype wheel. rotating with the movement of the auxiliary poise, anddevices for printing from the type on the main beam and type wheel.

2. In a recording weigh beam, the com bination with the main beam havinga printing portion with type on its upper side, and the main andauxiliary poises, of a type wheel rotating with the movement of theauxiliary poise, and devices for printing from the main beam and top ofthe type .wheel.

3. In a recording weigh beam, the com bination with the main beam havinga print ing portion with type on its upper side, and the main andauxiliary poises, of a type Wheel rotating with the movement of theauxiliary poise, a ticket holder above the type, and devices forpressing the ticket downward on the main beam and top of the type wheel.

4. In a recording weigh beam, the combination with the notched main beamand main poise and its pawl, of a ticket holder my hand, in the presenceof two subscribing witnesses.
